STREET-SWEEPER.

SPECIFICA'IION forming part of Letters Patent No. 644,739, dated March 6, 1900. Application fi1e l January 281898.- Serial No. 662,269. (No model.)

T0 0ZZ whom it may concern:

Be it known that we, ALTON H. GREELEY and CHARLES 0. BAR'ILETT, eitizens of the United States, and residents of Cleveland, county of Ouyahoga, State of Ohio, have invented eertan newand useful Improvements in Gutter-Sweeping Machines, of which we hereby deelare the followingto be a full, clear, and exact deseription, sueh as will enable 0thers skilled in the art to which it appertains to make and use the same.

Our invention has for its object to provide a sweeping-maehine whieh is adapted to clean the gutters next to the eurbing and in which the sweeping-brushes are loosely supported, s0 as to follow inequalities in the pavement, sueh as gutter-crossings, &e.

Our invention consists in the features of construction and combination and arrangement of parts, as hereinafterdescrbed, shown in the accompanying drawings, and specifica1ly pointed out in the claims.

In the accompanyng drawings, Figure 1 is a side elevation of our sweeping-machine. Fig. 2 is a plan view thereof, a p0rtion of the platform being broken away to show more clearly one of the brushes and its supports. Fig. 3 isarear elevation of the machine. Fig. 4: is a side view of one of the bearings or driving-shafts. Fig. 4 is an edge view thereof. Fig. 5 is a view in perspeetive of clutchlever and conneetions with the clutoh 0u rear axle. Fig. 6 is a plan view of pawl and ratchet ancl lever for raising the brush-shafts, and Fig. 7 is an end view of the same.

In the views, 1 is a frame mounted upon rear wheel-axle 2 and front axle X.

3 is aspur-gear mounted upon the rear ax1e and engaging the pinion 1 upon the intermediate axle 5. A wheel 6 upon this shaft engages a corresponding bevel-wheel 7 upon a longitudinal shaft 8, which is secured within suitable bearings 9dependngfrom the frame.

10 and 11 are rotary brushes diagonally mounted upon axial shafts 14, whieh are supported in bearings 13 on similar sides of triangular yokes 12, through the opposite sides of which passes the longitudinal shaft 8, upon which the yokes are supported.

Bevel-gears 16 upon the longitudinal shaft engage bevel-gears 15 upon the extremities of the brush-shafts.

A universal joint is shown at 17 in each part rotation to the longitudinal shaft through the intermediate gearing and thence to the brushes. It is desirable that the brushes should rise and fall easily by their own weight as they pass over uneven pavements, and hence the yokes and universal joints are employed 130 permit this free movement, so that the brushes may always rest upon the pavement however uneven the surface.

The brushes are lifted when not in use by means of drums 20 upon diagonal shafts 21 and chains 19, passing over the drums and attached to the shaft-bearings below.

A ratehet-wheel 27 is engaged by the lever 25 to turn the drum-shait, and a pawl R securely holds the drum wherever placed.

28 are elutches of anycommon form mounted upon the shaft 8 to engage the loose gears 16 01 release them when it is not desired to use the brushes. Another eluteh 29 is employed upon the axle-shaft 2, which Will disengage all the gearing therefrom when desired. This clutch is shown to be operated by lever 36, bellcrank 32, and links 31 and 33 and pin 30.

Having deseribed our invention, what we claim as new, and desire t0 secure by Letters Patent, is 1. In a ssreetsweeper, in eombination; a wheeled vehicle a longitudinal shaft mounted therein gearingconneeting said shaft with an axle of. the vehicle; yokes sleeved at 0ne side 0n said shaft; a brush-shaft mounted diagonallyin the ot-herside of each yoke; means for vertically adj usting eael1 brush-shaft, and a gear eonnection between the longitudinal shaft and eaeh brush-shaft; substantially as described.

2.
